ATTQRNEY.

It isa matter of common knowledge, that the final step in the process of polishing marble and other analogous surfaces, is to rapidly rotate a buffer head over said surface after placing a Flmixture of acid, powder and sulphur under the buffer, or on the surface to be polished. 'Ihese buffer heads are usually constructed of felt or rope, which is very expensive, due to the fact that they do not last very long for their purpose.

It is therefore the primary object of the present invention to provide a buffer head for the purpose above mentioned, which can be manufactured at a comparatively low cost, and one -1'5which possesses a maximum degree of efficiency.

5`of the head. Further, the corn shucks of each unit preferably extend substantially parallelwith the axis of the head so that the edges thereof engage the work, and so that the polish- `ing surface will effectively resist wear and de- Tterioration.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawing, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of this application like numerals of reference indicate similar parts in the several Views and wherein:

Figure 1 is a view in elevation of the buffer head forming the subject matter of the present invention.

Figure 2 is a bottom plan view.

- Figure 3 is a vertical sectional view.

Figure 4 is a perspective View of one of the Y units forming part of the polishing surface.

Referring to the drawing in detail, 10 indicates the circular head of the buffer, which is preferably constructed of wood and which may vary in diameter. This head is provided with a central passage 11 through which water or the like ows from a suitable source while the buier is in use. Bolted or otherwise suitably secured to the top of the head 10 is a metallic provided with annular slots 17 so that the water passing through the bore or opening 11 of the head can readily pass through the ring-like member into the units constituting the polishing surface. Surrounding the head 10 and depending therefrom is a retaining band 18, which of course is arranged in spaced concentric relation with the ring-like member 14,` as it is between the ring-like member and the retaining band 18 that the units 19 are closely associated.

In accordance with the present invention, these polishing units 19 are each constructed of corn shucks arranged in circular bundles, each being tied by an element 20 adjacent one end thereof. As each unit is positioned between the ring-like member 14 in the retaining band 18, it has its inner end adhesively secured to the under side of the circular head 10 as at 21. Each unit 19 projects an appreciable distance beyond the lower edge of the retaining band 18, and when all of these units are compactly arranged in position for use, they collectively provide a very eflicient polishing surface for marble, glass and other analogous plane surfaced material. By using corn shucks in the manner above described, in place of felt, rope and like material, a buffer head for the purpose above-mentioned can be very cheaply manufactured, and at the same time possess all the advantages derived from the use of such 'materials It is of course to be understood that the buffer head hereinabove described is adapted to be rotated at a very high speed, over the surface being dealt Y with, but this may be accomplished by any conventional type of means well known in the art.

While it is believed that from the foregoing description the nature and advantagesof the invention will be readily apparent, I desire to have it known that I do not limit myself to what is herein illustrated or described, and that such changes may be resorted to when desired, as fall within the scope of what is claimed.

What I claim as new is:

1. In a buffer, the combination of a mounting head having a depending peripheral retaining band and a depending ring-like member Within and in spaced concentric relation to said retaining band, and a buiing element consisting of a plurality of longitudinally disposed relatively short bundles of corn shueks tightly compacted in the space between the retaining band and the ring-like member and extending only slightly beyond the'lower edges of said retaining band and said ring-like member, Veach bundle con'- ssting of closelycompacted longitudinally disposed corn shucks, the lower ends of said *corn shucks forming a relatively firm buiiing element capable of withstanding applied pressure with-#l1 out appreciable distortion, there being a fluid passage through said head openin'g'withinsaid ring-like member. l

2. In a buffer, the combinationof a mounting head having a depending peripheral retainingr band and a depending ring-like member Within and in spaced concentric relation to said retaining band, and a buiiing velement consisting of a plurality of longitudinally disposed relatively short bundles of corn shucks tightly compacted in the space between the retaining band and the ring-like member and extending only slightly beyond the lower edges of said retaining band and said ring-like member, each bundle consisting of-r closely compacted longitudinally disposed corn shuekS, the lm 'gver ends of said corn shucksforming a relatively rm bufling element capable of withstanding applied pressure without'; appreciable distortion, there being a fluid rpassage through said head opening within said Vring-'like member, said ring-like member having numerous openings therethrough to facilitate lateral outward passage of iiuid therethrough to said bufllng element.
